Dry eye disease (DED) is a common comorbidity in patients undergoing cataract surgery and can adversely affect tear film stability, thereby impacting the accuracy of preoperative biometry and postoperative refractive outcomes. To address this concern, a study evaluated the perioperative use of perfluorohexyloctane ophthalmic solution (PFHO), a long-acting tear film stabilizer, assessing its effect on biometry accuracy, refractive predictability, and ocular surface outcomes in 97 patients with DED undergoing cataract surgery. The study found no significant difference between manifest refraction and predicted refractive error (−0.027 ± 0.167 D), with 94.2% of eyes showing prediction differences within ±0.3 D after PFHO treatment.
A higher proportion achieved accurate IOL power calculation within ±0.50 D post-treatment (83.7% vs. 72.1%). PFHO significantly improved dry eye signs and…
